[Question] Too many values to unpack issue

[sohv]

Hey,
I wrote the below code to initialize an instance of SpaceInvaders environment, run 1000 iterations to perform a random action from the sample space and render the environment in real-time.
import gym
env = gym.make("ALE/SpaceInvaders-v5")
env.reset()
for _ in range(1000):
env.step(env.action_space.sample())
env.render()
env.close()
But, I am encountering an error on env.step line that states ' ValueError: too many values to unpack (expected 4)'. I tried modifying that line to return 4 values and also downgraded gym version to check if it's working but to no use. Can you help me resolve this issue?

I can't replicate the problem with the code provided.
Are you using gym with another project?
